Chunling Liu, Jian Zhu, Haiyan Liu · 2017
In the process of satellite network communication service transmission and distribution, due to the limitation of the system cache space can cause the congestion effect, it easily lose the data of high importance or timeliness. Aiming at the problem of network congestion effect, based on RED (Random Early Detection) algorithm, M_TSPAQM(Queue Manage Algorithm Based on Priority of Multiple Terminal and Service) is proposed. According to the urgency of the operation, the algorithm can choose to discard the service according to the different drop probability, and a multi-terminal and multi-service priority model is established. The simulation results show that, compared with the RED algorithm, the average loss rate is reduced to about 0.124% of M_TSPAQM algorithm, the average throughput per second is higher than about 40 packets. And when the concurrent business comes, it is also able to reduce the time delay jitter, t+o meet the demand for the transmission of complex satellite terminal services with a burst.
